Beit known-that I, GEORGE KissAM-CooKE, a citizen of the-United States,residing in Jamaica, in the borough offQueens, oityand State of New York, have invented acert-ain new and useful .Improvement in Measuring-v Faucets, of Whichthe followingis a specifica-v tion.

This invention relates yto a measuring-faucet, and, as set forth herein; is disclosed more particularly in connection with la faucet off the-self-closing type. T herearel certain im: portant features,.however-, which are .capableof employment with other* constructions of faucets-and if desired, withsuitable-,forins of4 valves. e

Prominent objects of theinvention are the accurate measuring of determined quantities i of liquid and dispensingA of the lsaine in a simi-l ple and convenient'm ann er,` facilityforadjustably regulating Vthe quantities y of .liquid measured, efficient liquid -level indication, and. air-venting provision, avoidance ofobi-.

jectionable overflowat the measuring-.cham-- ber, positive seatingoffthe va'lveprovision, and high efficiency, simplification, and kdura-- bility of the construction generally.

`With. the above and other -purposes in view. the invention comprehends a' novelr arrange-y ment of faucet :or valve and' measuring-chaml-v ber coactive therewith, Athe rne'asuring-chain-4 ber beingin communicationwith the liquidsupply wheny said faucet or valve-isv closed,

but adapted to discharge'its measured quantity ofliquid through the faucet or valve when the latter-is opened ,1 together with-` means for adjustably regulating the quantity of liquid admitted to the measuring-charnber:l upon each closure of the said faucet or valve..

As previously intimated, the improvement involves other important features'which in addition to those alluded to are clearly eX- plained in the subsequent detailed description.

The invention is shown'a'nd will be described as adapted for service in connection with a sof1 a-waterfountain in dispensing a flavoring-syrup; butit will be understood that the improvements are not restricted to such use.

' In the accompanying drawings, forming part of this specification, Figure lis a vertical sectional viewof a part ofl a syrup-reservoir equipped with one form ofmyinvention.

Fig. 2 is avertical eleva-tion of the measuring-1 chamber and .certain appurtenances, viewed'I inf a position at ariglit .angle to `that in which "theyappeanin thepreceding figurel Fig; 3 is.a-v1ew similar to Fig. 1 and disclosing anotherfform of the invention. Fig. 4 .is a detaill sectional Viewv illustrating a novel provision` foradjusting the valve-seat from the rear.

Similar reference characters are employed todesignatecorresponding parts in the sev- `eralifigures -of the drawings wherein they occur. f A

' Referring-more particularly to Figs. l and 2t'lie bottom a: of thefsyrup-reservoir, iinmediately adjacent to the front wall A of the latter, containsacircular opening sufficiently ample-to admit of: the readyinsertion therethrough land securement .therein ofthe externally-threadedfend `portion b o f an elbow B by, nuts and yielding washers in the usual manner, the Whole serving to provide a firm 1 .liquid-tight joint.

If desired, cer-tain par'ts'of the novel meas- .uring-faucet yma()T be-of some suitable noninetallic material.. f Hence' the elbow B,nut

t?, and'washerb'* canl be of vhard rubber,

while-thewashers btb2 can` be of moderately sof-t rubber. e

The lower forwardl part t6 of the elbow B is internallythreadedvffor vthe:engagement withiii the rsame of the eXteriorly-threaded stem c, carried by and horizontal-ly projecting from therear of the faucet-bodyl The faucet-'body comprises a y'rear section f vC and forward section C ,relatively independgof which is Jalined with a horizontal passage ce, rearwardly extending through the section and the stem c thereof, communication bing thus established between the faucet-chamber' andthe interior of the-syrup-reservoir.

integrallypresented by the body-section C is a dependingn'o'zzlef5 and forward hollow extension C, the latterhaving an externally-flaring extremity c7. The recess withv in the extensionis intersected by a bottoni.

IOO

' longitudinal groove c".

Snugly, but slidinglv, bearing within Vthe extension recess is the hollow shank of a push-button C7, said shank having a lower spline or feather c within the. groove cs for preventing the rotation of the push-button, While permitting the free longitudinal movement thereof.v

l/Vithin a properly-recessed portion of the section C', contiguous at the rear of the -noz- Zle, is a tubular lyielding section, the forward end of which bears against a shoulder c1, while its rear end c projects a short distance within the larger recess of the faucet-body to constitute an expansible valve-seat in reversed rclation with regard to the seat in the section C. i n n Secured in the head of the push-button C7 is the forward end of a valve-spindle C? of comparatively small diameter and of such length that it extends rearward successively through the button-shank, the recess within the extension C, and through an opening centrally in a washer cl2, bearing at the inner end of the extension recess, said spindle continuing through the forward wall of the'nozzle, across the latter, and through a'liberal` aperture in the rearwall thereof, through the adjacent tubular section, and finally terminating at a point well within the-large recess within the faucet-body.

In threaded engagement with the spindle is a body the respective ends of. which are rounded to present primary and secondary valves C" 'C10 in coactive relation with the valve-seats c11 and c5, so that one valve will seat as theother is unseated. The primary valve is normally maintained seated and the valve C1 unseated through tliemedium of a coiled expanding-spring contained within the recess of the extension C" and also within the hollow shank. Suitable means for guiding the inner end of the spindle and maintaining the alineinent of the same may be employed.

With regard to the parts described as being carried by the .section C, including the primary valve C, it may be stated'tliat they embody an arrangement of features some-` what similar to that of the self-closing faulcet disclosed'in a patent of mine and dated August 1, 1899, No'. 630,184, to which patent reference may be had for a complete understanding of the construction and operation thereof.

It will be observed that the enlarged part C3 of the section C is amply provided m the matter of threads for Aengagement by the coupling. This admits of a considerable range ofadjustment relative to the section C. and thus enables the sections to be nicely adjusted for insuring the accurate liquidtight seating of the secondary valve and also.,

to permit the adjustable variation of the measuring capacity of the valve-chamber.

The coupling has tapped thereinat the upper side thereof an opening which comiiiui'iicates with the interior recess iii the Valve-body, and in said opening is screwed the lower end of a small vertical tube D, ex-

The central porv with a dome-shaped contraction e, merging A in a vertical tubu ar extension e/ of comparatively restricted diameter and which terminates at its upper extremity in a,contracted part e2, containing a perforation. The lower end of the chamber is confined liquid-tight within the base-flange d, so that said chamber and its parts will be properly supported in position. intimately incasing said chamber and its extension e is a thin metal sheathing E, the lower portion e3 of which is slightly expanded to snugly take over and embrace the, flange d, and thereby contribute to support the sheathing, as well as the chamber E f and its parts.

"At its forward side the sheathing E has a vertically-extended opening e4, appositely located with respect to the chamber E, said opening e4 being intersected at its top by a vertically-elongated slot e in corresponding relation to the extension e. The thin metallic sheathing thus described constitutes a guard or shield for protecting the glass chambe'rvand its extension from injury and at the same time presents a medium contributing to support such chamber and said extension in proper position. The opening el and slot e5 conjointly provide a sight-opening through which the iquid within the glass chamber and its extension e can be readily observed. That portion of the glass chamber exposed through the opening e4 may have a series of graduations thereon for indicating various quantities represented by different liquidlevels within said chamber.

It will be readily gathered from the description immediately preceding that the chamber E and its upper extension are designed to form a measuring-chamber. With the parts represented in the position shown in Fig. 1 it will be comprehended that syrup can pass from the reservoir by way of the tube B and flowing past the unseated valve C10 will ascend in the tube Band enter the chamber VE, the inflow being continued until said chamber is filled and the liquid has attained a height in the extension e proportionate with the level in the reservoir. As the liquid enters and rises in the measuring-chamber ISO the air within the latter will be'displaced and expelled through the opening in the upper end of the extension e', thus furnishing a proper vent for the chamber. The base D and other parts of the measuring-chamber can have previously been vertically adjusted on the tube D, so as to regulatethe quantity of liquid to be measured, which quantity is represented by the vamount of liquid Within the chamber and its extension e above the upper end of the tube D plus the liquid in said latter tube anda limited amount contained in the body-recess behind the valve C. Therefore in providing the measuringdivisions such excess liquid is taken into consideration.

When it is required to draw the quantity of liquid thus measured, pressure is exerted on the push-button, which has the effect of bringing the secondary valve liquid-tight to its seat and unseating the valve C9. By this means communication `between the syrupreservoir and the body-recess and measuringchamber is absolutely cut off` and communicationestablished between the measuringchamber and the discharge-nozzle. Consequently the measured amount of liquid in the chamber E andits extension e above the upper end of the tube D will be withdrawn and discharged through the nozzle. Of course pressure on the push-button will be maintained until the measured quantity is exhausted. Upon releasing the button the expanding-spring will operate to restore the valves C C10 to their former positions, thereby cutting off communication with the nozzle and permitting a further quantity of the syrup to be measured off in the chamber E, its extension, tube D, and the valve-chamber. The extended character of the upper portion of said measuring-chamber obviously prevents objectionable overflow.

In order to maintain communication between tlie tube D and interior recess of the faucet-body, notwithstanding the relatively adjustable character of the sections C C of the latter, the contiguous ends of said sections are provided with external depressions cl2, thus avoiding angles that would interfere with the unrestricted communication between said tube and the body-recess.

From the description thusfar it will be appreciated that a measuring-faucet embodying my improvements can be conveniently and securely connected with a syrupreservoir, the measured quantities'of liquid regulated by the position of the measuringchamber upon the tube D, and that the predetermined quaiitity of liquid in the measuring-chamber can be isolated from the liquid in the reservoir and withdrawn in an expeditious manner. The weight of the liquid in the measuring-chamber aids when said liquid is discharged to cause the flow of the liquid from the valve-chamber, and thus etticiently discharge. Furthermore, the condition and quantity of the liquid within the measuring-chamber will at all times be under convenient observation and proper venting of the liquid-chamber afforded.

The parts comprising such measuringchamber are of 'such character and relatiorl that-they may be easily fitted together and adjusted and can be conditioned to avoid deleteriously affecting the syrup. Additionally, the nature and connection of the portions comprising t-lie measuring-faucet are such as to permit of the ready substitution of repair parts and thorough cleansing, when required, of all portionsof the construction.

In Fig. 3 I have illustrated a form ol' the invention as being applied to a syrup-reservoir, whereby the self-closiiig faucet. proper, C11, projects horizontally from the front Wall A of the reservoir immediately contiguous to the bottom a thereof. In this construction the self-closing faucet while of slightly-modifiedv character still embodies the essential principles of the spring-projected push-button cl2, slidinglv guided at the front end of the faucet and having attached thereto the forward end of the horizontally -vextended valve-spindle cl3, carrying the primary valve C12, coacting with a yielding seating for controlling the immediate communication with the nozzle C13. The enlarged rear portion of the valve-body carries the externally-threaded tubular stem c, the projecting part of Which extends through an opening in the reservoir-wall and engages Within the forward part b7 of acasing B of the character land configurationsubstantially represented. This casing contains a relatively enlarged interior recess b, and engaged within a threaded opening in the inner end b" of the casing is a short inlet-tube B2, one end of which, as will be seen, is in apposition with respect to said casing-recess and is iiiteriorly out away to permit the expansion of the inner projecting end blo of a tubular flexible valve-seating, the other end of which bears against a shoulder b interiorly within the tube B2. The external end of the latter has a flange b, to facilitate the rotation of such tube by the fingers.

It will be noted that the valve-spindle c is of such length that its inner extremity carries a secondary valve C14 within the casingrecess bs, the expanding-spring at the forward part of the faucet serving to normally maintain said valve C14 in an unseated position relative to tlie seating b1", While the valve C12 is in a seated position. It will be comprevhended that by revolving the tube B2 to cause it to move inward or outward within the casing B the position of the valve-seating blo can bealtered to insure the accurate liquid-tight seating of the secondary valve.

In this construction the measuring-chamber 1n itself has no adjusting provision, it having IOO IIO

a capacity l'or a definite quantity of liquid and sinip v comprises a circular base Di, provided with a short threaded nipple d, cngaged within an appro )riate opening'in thc top of the casing, the g ass measuring-chainbei E being connected at its lowerend .with said base and having the upper piolonged extension ei.

By contracting thelineasuring-chamber tov thev limit of the tubular cxtensi'onjas shown` -ing being ta pcd at its upper'sidefor the engagement o the lower threaded end'fb12 of a flanged nip le B4, the upper tlireaded'portion Zi of whic i extendstlirough anV opening in the reservoir-bottoni, yielding gaskets 615 and an upper nut b1 securing afli uid-tiglit lconnection lfor sai-d nipple with t e reservoir in an obvious manner.

The body C15' of the spring-closed faucet has f a vrearwardly-extending Ltubular lexten- `sion c, which is screw-engaged within an "opening therefor in the iorward headof the casing B3, ayielding washer b" being interposed between such casingand body'Cs'to promote a tight jointat this point.

Screwed into an opening' inthetop` of'the enlarged rear part of the faucet-body is the lower reduced end of a short vertical tube D3, the upper part of which is of enlargedy diameter and externally threaded for adjustably mounting thereon the base D4 of the glass measuring-chamber E3. In this construction the measuring-chamlier may be restricted to the form of a simple tube and the capacity of the valve-chamber varied Vto suit `requirement.

C16 C" are the primary and secondary valves, respectively, both carried by the spindle c1, the primary valve being normally held to its yielding seat c17,'wliile the latter is in unseated relation with respect to the tubular seat C18. This latter is carried in the forward end of the plug B5, longitudinally screw-adjustable in the rear open end of the The Aexternally-projectingpart A casing Bf. of the plug is enlarged and -peripherally milled to present a head B,'fa`cil`itating the adjustment of the plug by the fingers from a position at the rear. Palpablyby manipulating the plug tliepositioii of the valve-seat e1s can be adjusted to insure'the accurate seating oiA the secondary valve. The plug has a peripheral opening or slot to adapt it 4tion irrespective oi the plug ad Because tor communication with the upperccnuec- `uistinent. 1

The advantage of having the tubular `yielding section forming the seat of the secondary valve project within the rear' iortion of the` valve-chamber is tirata cut-'ott is established eveiibefore thebutton is pressed to thelimit ofitsiiiward movement."` Thus the'objection .incident-to not pressingthe button toits; full limit is largely overcome.

I do not 4limit myself to thexparticular construction and f arrangements of vparts shown and described, but reserve the right tok all modifications fairly within thescope of my invention,
